Dapr captures metrics and traces that can be sent directly to Datadog through the OpenTelemetry Collector Datadog exporter.
Using the OpenTelemetry Collector Datadog exporter, you can configure Dapr to create traces for each application in your Kubernetes cluster and collect them in Datadog.
Before you begin, set up the OpenTelemetry Collector.
Add your Datadog API key to the ./deploy/opentelemetry-collector-generic-datadog.yaml
file in the datadog
exporter configuration section:
data:
otel-collector-config:
...
exporters:
...
datadog:
api:
key: <YOUR_API_KEY>
Apply the opentelemetry-collector
configuration by running the following command.
kubectl apply -f ./deploy/open-telemetry-collector-generic-datadog.yaml
Set up a Dapr configuration file that will turn on tracing and deploy a tracing exporter component that uses the OpenTelemetry Collector.
kubectl apply -f ./deploy/collector-config.yaml
Apply the appconfig
configuration by adding a dapr.io/config
annotation to the container that you want to participate in the distributed tracing.
annotations:
dapr.io/config: "appconfig"
Create and configure the application. Once running, telemetry data is sent to Datadog and visible in Datadog APM.
